What are analysts saying

As equity markets continued to tumble, one digital-currency proponent and smart-contract user said major coins would provide investors with a bet against what is lining up as a bumpy 2019 for financial markets.

“There’s a growing list of investment tailwinds to consider for 2019. These include significant trade tensions, rising interest rates, political uncertainties, including Brexit, and complacent financial markets,” said Ian McLeod of Thomas Crown Art, a blockchain-based company that promotes smart contracts for art, in a morning note.

“Against this backdrop, we can expect cryptocurrencies will increasingly be seen as investors’ ‘safe havens’ in 2019 and beyond.”
